Dosage and Application Instructions

Concentration: 10% solution = 100 mg/mL amprolium

Treatment Dose:

Standard Therapeutic Dose:
10 mg/kg body weight once daily for 5 days.

Dose Calculation:
10 mg/kg ÷ 100 mg/mL = 0.1 mL/kg
0.1 mL/kg ÷ 2.2 = 0.045 mL per lb body weight

Final Treatment Dose:
0.045 mL per lb body weight once daily for 5 consecutive days.

Water Medication (Herd Treatment):

Provide approximately 10 mg/kg per day through drinking water for 5 days.

Water concentration must be calculated based on:

• Average body weight
• Estimated daily water intake

This ensures each animal receives the full 10 mg/kg daily dose.

Prevention Dose:

5 mg/kg body weight once daily during high-risk exposure periods (up to 21 days).

5 mg/kg ÷ 100 mg/mL = 0.05 mL/kg
= 0.023 mL per lb body weight

Preventive programs should be implemented under veterinary supervision.

Dosage Frequency:

• Once daily administration
• Treatment: 5 consecutive days
• Prevention: Daily during risk periods (commonly up to 21 days)

Dosage Duration:

• Standard treatment course: 5 days

• Preventive programs: Duration varies based on exposure risk and management conditions and should be confirmed by a licensed veterinarian

120 mL (4 oz): Ideal for individual calves or small herd treatment.

240 mL (8 oz): Suitable for small groups of calves.

960 mL (32 oz): Best for medium-sized herds or seasonal outbreaks.

FAQs

What does Amprolium 10% Liquid Solution treat in cattle?

It is used to treat and control coccidiosis caused by Eimeria species, a common cause of diarrhea and poor growth in calves.

How quickly does Amprolium work?

Improvement such as firmer manure and improved appetite is often observed within a few days, but the full 5-day treatment course should always be completed.

Can Amprolium be used preventively?

Yes. A lower daily dose (5 mg/kg) may be used during high-risk periods such as weaning, overcrowding, or transport stress. Preventive use should follow veterinary guidance.

Is it safe for young animals like puppies, kittens, chicks, or baby livestock?

It is commonly used in young calves where coccidiosis risk is highest. Use in very young or stressed animals should follow proper weight-based dosing and veterinary supervision.

Is it safe for pregnant animals?

Use in pregnant cattle should only be done under veterinary supervision.

How is it administered?

It can be delivered through medicated drinking water for group treatment or administered as an oral drench for precise individual weight-based dosing.
